Zusammenfassung:	The utility model discloses an anti-abrasion gear pump for balancing radial force of side plates, and relates to the technical field of gear pumps. Comprising a pump body, a gear set cavity and a gear shaft cavity are formed in the pump body, a gear set is arranged in the gear set cavity, a gear shaft is arranged in the gear shaft cavity, side plates are arranged on the two gear end faces of the gear set in an attached mode respectively, and an oil duct groove is formed in the side wall of the end, close to the gear shaft cavity, of the gear set cavity. An oil inlet and an oil outlet are formed in the two sides of the pump body respectively, and the oil channel groove is formed in the side close to the oil outlet and communicates with the oil outlet. The oil duct annular groove is formed in the tooth cavity of the pump body, oil in the oil duct annular groove is communicated with high-pressure oil borne by the side plate, so that radial force borne by the side plate is balanced, abrasion of the side plate in
